Search on "Tennis Court Paint" and you will get all kinds of interesting info...some advertise minimal surface prep and they are non-skid . Most appear to be acrylic. I haven't used any but am considering for a schoolyard project as well ....Tom

But it is toxic as it is applied, then dries hard, safe and durable. Any concrete/plaster provider should have good advice about products that adhere to asphalt.

( My daughter is a pupil at that school.) I have been liaising with the art teacher, and the suggestion is that one or more students studying art would mark out the layout of the dial on the tarmac/asphalt ground, and then paint on it. So both a scientific and artistic project. The difficulty we face is that the tarmac/asphalt surface is quite grainy and not good to paint on. Do you have any advice on how to get a good smooth outdoor surface to paint on (and we want the surface to retain the paint) ? Any advice would be appreciated.
